GOV E R N O R Specification of Letters Patent.

Patented June 12, 1906.

Application filed October 2,1905. Serial No. 281,036.

To all whom it may concern.-

Be it known that I, FREDERICK OSSIAN BALL, a citizen of the UnitedStates, residing at Plainfield, in the county of Somerset and State ofNew Jersey, have invented new and useful Improvements in Governors, ofwhich the following is a specification.

This invention relates to governors; and it consists in certainimprovements in the construction thereof, as will be hereinafter fullydescribed, and pointed out in the claims.

The invention is illustrated in the accompanying drawing, wherein Amarks the fly-wheel of an engine, which in the construction shown formsthe rotative carrier of the governor. The governor shown is providedwith two weights B and O. The Wt ght B comprises the arm 12 and Weightedends I) and 6 It is pivoted on the carrier at The pin E for operatingthe valve-rod (not shown) is carried by this weight and operated in theusual manner. The Weight C comprises the arm 0 and Weighted ends 0 andIt is pivoted on the carrier at c. A link D connects the weights B andC. These weights operate in a manner common to governors of this classand form the centrifugal element of the governor. The valveactuatingmechanism is driven by devices (not shown) arranged at the center E.

A spring-rod F is connected to the weight 0 at f. This rod has thescrew-threaded end f. The cross-headf is arranged on the rod and issecured in adjustment thereon by the nut f Y I The spring G is connectedby the rods 9 and g with the cross-head and carrier, respectively, andthe spring H is connected to'the cross-head and carrier by the rods hand h, respectively. These springs are arranged at an angle to eachother. The spring-rod F, being free to swing at f, takes the directionofthe resultant of the forces exerted by the springs G and H. The spring His preferably formed of larger coil than the spring G, and when so madeit increases in resistance less rapidly when stretched than the springG, and in consequence the end f of the rod F is made to swing toward thespring G as the Weights swing outwardly, thus, in effect, changing thebase of the centripetal element. In this way the length of the arm fromthe pivot G is automatically changed by the change in the base of thespring or centripetal element, and in consequence a shorter spring maybe used with the same result as a longer spring with a fixed base. Byvarying the lengths of the springs, their relative strengths, and theangle between them other variations in the action of the springs may beobtained. This arrangement of springs also lessens the side swin of thesprings under the influence of centri ugal force and gravity.

What I claim as new is 1. In a governor, the combination of a rotativecarrier; a governor-weight mounted thereon; a spring-rod connected tothe weight; and two springs arranged to exert force in directions at anangle to each other and con nected to the rod and the carrier.

2. In a governor the combination of a rotative carrier; agovernor-weight mounted thereon; a sprlng-rod connected to the weightand two springs arranged to exert force in directions at an angle toeach other and connected to the rod and the carrier, said springsvarying in resistance with a given stretch.

3. In a governor, the combination of a rotative carrier; agovernor-weight pivotally mounted thereon; a spring-rod connected withthe weight, and two springs arranged to exert force in directions at anangle to each other and connected with the rod and the carrier, saidsprings varying in resistance with a given stretch, and arranged toswing the rod as the springs are extended in a direction tending to varya relation between the rod and the weight to shorten the eifective armof the weight as the springs are extended.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

FREDERICK OSSIAN BALL. Witnesses:

A. K. SMITH, E. M. KUNTz.
